sraivciiio'N.

To all whom 'it may concern.' Be it known that I, FRANK OSCAR Woon, a

citizen of the United States, residing at Brownsville, in the county of` Dodge-and State oit1v Wisconsin, have invented certain' new-and useful Improvements 'in Stanchf ions; and I do declare the; following to be a. full, clear, and exact description of the invention, such as will enable othersslrilled in. the', art to whichit appertains to make 'and use the saine.

This invention relates to stanchions,'and' the object of the same is to effect improve-f ments in the meansA whereby the hinged yoke member visfheld closed or permitted to open. ..With this end in view the invention consists of certain novel' features of construction, and the'comhinat-ion and arrangement of parts as will be more fully described and' claimed. f Y

In the accompanying drawings: Figure 1 ,is a front view ot' my improved stanchion showing the latter in closed position; Fig. 2 is` atop plan view thereof; Fig is a front View of the stanehion with'parts of the upper `supporting bars removed and illustrating.

,the position yol the stanchion when; open; Fig. et is a. vertical -cross section of the stanchion taken on the line H of Fig. 1;

Fig. 5 is a detail horizontal section throu h the stanchion operating mechanism `andi e upper end of the stanchion taken on'the line 5--5 of Fig. 3; Fig. Gis a view similar to Fig. l showing two stanchions arranged'in series and illustrating the manner in which one of the saine is held in closed position while the other is opened by the operating mechanism. Fig. 7 is a similar View illustrating' the manner in which one or more of the stanchions may be independent-ly opened without opening the lrest of tlie stanchions in the series; fliig. 8 is a horizontal sectional view of one of the stanchions and Aits sup-` porting mechanism taken on the line 8 --8 of Fig. 3; Fig. `9 is a detail perspective View of the lever ttor operating the stanchion fastening and releasing mechanism and the link which connectsthe lever thereto; Fig.-

10 is a similar' view of one 'of the independent stanchion locking and releasing devices;

Fig. l1 is a similar .View ot' one of the stanchion supporting blocks t-lieparts there-Y ot' being separated.

Referring more particularly to the draw! ings, l denotes the base or coping on which my improved stanchions are supported and which maybe formed `of wood, concrete or other suitable material.

l Spacedgsuit distances apart andA secured at their" iies of supporting standards 2 tothe upper stanchion supporting block 4 which 'is formed in two sections each of which has its ,upper end offset to form a bearing lug -5,

said lugs having in their inner sides semi` .circular recesses which when the lugsl are brought together.l will register and 'form' a bearin opening for the upper end of the stanchion wherebythe latter is loosely supported as will be hereinafter more fully de- The neck engaging portion or yoke of the scribed. Y

stanchi-on comprises a stationair. member 6' and a hinged or opening mein r 7. .The stationary member 6 of the yoke has on'its upper end an upwardly projecting support *ing stud 8 having on its upper end a head 9.

The stud`8 for a short distance below the lhead is cylindrical and below the cylindri cal portion the stud is semi-,cylindrical as shown. The cylindrical portion of the stud has a pivotal or revoluble engagement with the bearing aperture in the lug 5 of the block 4 whereby vthe upper cud 'of the yoke vis -revolubly `and loose y supported to permit the yoke to swing freely in all direc# tions an to revolve between the standards 2.- `Formed on the upper end of the pivoted .member (i ofthe yoke at the lower end4 of the stud 8 are a pair of laterally projecting apertured' lugs l() the purpose of which will be hereinafter described.

i The opening member 7 of the yoke has a hinged connection at its lower end with the lower end of the stationary or pivoted'member t3 with which it co-acts to "form the yoke. vThe upper end of the member 7 when in a. closed or operative position engages be tween the laterally projecting lu upper end of the lmember (i and7 is thereby heldin engagement with or against lateral es 'l0 on the movement at its upper end. Ft'irined on the y"upper end of the member 7 is an upwardly projecting semi-cylindrical stud il which when the member 7 of the-yoke is in closed los position, -engages the semi-cylindrical por- A 'the upper ends of which arexconnected, to

'tioniiof the stud 8 on the member 6. The

stud 11 projects between and has a sliding engagement with the bars 3 when the member 7 is swung tov an open or closed position.v The members 6 and 7 of the yoke are pref-l the lower endsl of themembers 6 and 7l of the yoke, while the lower .ends'of the chains are preferably connected to an eyebolt 14 which has aswiveled connection -with a iastening plate 15 secured to the to fof vthe j base or c'oping'lk midway betweer'rt e standards 2- as shown. By thus connecting'v the lower end of. the4 yoke to the coping 1 the yoke is permitted to swing freely in all directions.

. Slidably mounted on the upper support.- ing bars 3 of-the stanchion isa yoke open- 'ing and closing mechanism comprising a pair of bars 1,6'wl1ich are' preferably Aformed of angley iron and which are spacedfapart the same distance as the bars 3 andhave a sliding engagement therewith. The bars 16 extend the entire lengthof the/.bars 3 and row of stanchions supported thereby and secured between the bars 16 adjacent tov one side ofthe space between-,the standards. .2 of each of the, stanchions is a spacing block 17 having formed integral therewith a depending bracket 18 which'extends downwardly between the bars 3 andbetween the block 4. and the adjacent standard 2 for a purpose hereinafter described.` Pivotally secured between the bars16 adjacent to and spaced a suitablevdistance from the studs 8f and 11 on the upper end of the yoke isa combined stop and yoke closing and releasling member 19 which is in the form of a block having on the lower side of its free end a depending lug 20'which, when the block is in a closed and operative position member 19 it will be seen that when the projects downwardly between the bars. 3 and in position to engage the upper end of the stud 11l or the hinge member 7v of the yoke. Theend of the block' and adjacent end .of the lug 20 have formed therein a vertical groove `or notch 21 which receives therounded outer side of the stud 11. On the upper side of tlie block 19 is secured a plate 22 the ends of which project beyond the sides of the block and engage the upper edges of the bars 16 when the block is swung downwardly to an operative position andthereby limit the downward movementl of the block. By thus arranging the block or bars 16 are shifted in one direction lon the bars 3,V the block 19 and -lug 20 will be moved back'or away from'the studs Y8 and 10 of the yoke members and will thus permit the member 7 to swing outwardly o r away from the member 6to an 'open osition 'as is clearly shown in Fig. 3 o the drawings. When the bars 16 are shifted in direction the engagement of 4 .the Opposite Vthe lug 20 .with the stud 11 will swing the vmember 7 offthe yoke back to a closed position in'wliicll position the member 7 will remain' until the bars 16 .are again vshifted to open the yoke v The bars 16 are shifted to openand close the yokes of the stanchions by 'a lever 23 having a right angular oifsetinner endwhich is pivotally,` Asecured to the upper end of the standard 2 at one end of the row of stanchionsand which is connected by a pair of divergin'g' links 24 to the adjacent end of the bars-16 whereby when the lever 1s swung upwardly, said bars 16 and the'blocks 19 carried thereby will 'be shifted in the proper-direction for bers 7 of all .of the yokes in the vrow of stanchions toswing. to open' positions. When the lever is swung downwardly the bars 16 and block- 19 will be shifted .in a reverse die permitting the memrection which-will cause the ylugs 20 on the blocks 19 to swing the hinged members 7 'of the entire .row of yokes to a closed position.

Should it be desired to prevent the opening of one or more of the yokes at any place i along the line of'stanchions and thus prevent the releasing ofthe animals fastened thereto, I provide zstopl pins 25 which are lengaged with alined apertures 26 formed in the bars 3 adjacent to the outer sides of the s tuds 11 when the latter arein closed position,

venting the opening movement of the yoke 'members 7 when the bars 16 and block 19 are shifted to release the hinged members.

of the other yokes in the manner described.

Y WherA it is desired to release one or more of the nanimals -at any point along the line of stanchions without releasing the entire row it is simply necessary to swing the blockv 19 and the lug 20 upwardly from between Vthe bars 3 and above the bars 16 as clearly shown in Fig. 7 of the drawings whereupon the hinged member .7 of this yoke will be permitted to. lswingy back to an open position. When the members 7 are thu-s swung open, the 'opening movement thereof is limited by the engagement of one of the pins 25'with alined apertures 27l whichare also.

formed in the bars 3 a suitable 'distance from the apertures 26. When the pin 25 .is thus arranged the stud .1,1 on the outer end of the yoke member. 7 will engage the pin which will limit the opening movement of said member as will be readily understood.- j In order to'prevent -,the animals when entering the stalls; from passing or projectsaid pins thus holding the studs l 11`1n engagement with the studs 8 and prelif ' their 4heads through the space between the pivoted or stationary member 6- ofthe yokcs and the adjacent standard 2 of the stanchions, when the yokes are in an open position, I preferably provide a stop or clossaidmember being member forthis space mg 1n the form of a vertical postor standard 28 which preferably corresponds to the V.standards 2 towhich the post 28 is hingedly attachedby means of upper and lower supi porting arms 29 and 30, said arms having in their inner ends apertures which receive the standard 2 and in their outer ends socketsv 31 which receive the ends of the posts 28, sai-d posts being secured in the sockets in any suitable manner. On one side of the upper arm 2 9 is formed an offset apertured 1ug32 to which is pivotally attached one end of a segmentalpost operati 'plate or link 33, the opposite end of whic is pivotally connected to the lower end of the de block'l whereby when the latter is shifted by the bars 16 when said bars are moved to permit the yokes'to open, said links 33 will `swing the arms 29 and 30 and the post 28 inwardly, thus bringing the latter to a position between the stationary member4 of the I yoke andthe adjacent standard 2 which will effectually prevent the animal from passing or inserting its head through this space.

v Theposition of the member 7 when open will prevent the animal from passing or projecting its head throughthe s ace 'between this side of the yoke and t e adjaent sta11dard'2 sojthat the animal must of necessity pass its head through between the r members 6 and 7 of the yoke and .in position to be 'fastened when the movable member is `drawn back to a closed position as will be readily understood. When the bars 16.are

' shifted to bring the members 7 back to a closed position, the movement of the block 17 and bracket 18 will through the link 33 again swing the arms 29 and 3() and the pest 28 out of the space between the members 6 of the yoke and the adjacent standard 2 thus leavlng this space open to permit the yoke to swing freely between the standards as the animal moves its head from side to side.

From the foregoing description taken in connection with the accompanymg drawings,

the construction and operation of the invention will be readily understood without rev quiring a more extended explanation. 4
